FIELD: communication.
SUBSTANCE: invention relates to internal home communication systems, specifically to home communication system with door (1) and home stations (2-5). For this purpose, all stations (1-5), as well as power supply unit (6), are connected to bus (8), through which both communication and power supply is carried out. Bus is divided into sections (16, 17), which are connected to each other by means of separation areas (18), which acts on power supply, and not on communication. Each section (16, 17) of bus is associated with its own power supply unit (6, 14), as well as its own power coordinator (7, 15). Invention also provides power coordinators (7, 15) for controlling coordinated power consumption of stations (1-5), which are provided with current values of power consumption of stations (1-5) and maximum tolerable power load of power supply units (6, 14) and which communicate with stations (1-5). Stations (1-5) declare/request their future demand in energy from power coordinators (7, 15), and power coordinators (7, 15) based on their power consumption values and maximum allowable power load of power supply units (6, 14), decision is made, whether requested demand in energy can be provided to power supply units (6, 14).
EFFECT: enabling control of coordinated power consumption of stations through a power coordinator.
